Coupling agent recovery equipment for pressure vessel inspection and inspection system thereof

The utility model discloses coupling agent recovery equipment for pressure vessel inspection and an inspection system thereof, which belong to the technical field of nondestructive testing of pressure vessels in nuclear power stations, and comprise a collecting device arranged on the outer side of the pressure vessel, and the collecting device is positioned below a welding seam of the pressure vessel, so that a splashed coupling agent can fall onto the collecting device. And the collecting device comprises a liquid collecting tank which is obliquely arranged and a connecting piece. According to the coupling agent recycling device, the splashing and falling coupling agent is collected through the liquid collecting tank movably installed between the pressure container and the condensation pipe, the coupling agent flows into the coupling agent collecting tank of the pressure container along the inclined liquid collecting tank to be recycled in a centralized mode, and the coupling agent recycling device is conven
